Very nice!
The Eiffel Tower, deconstructed with @claudeai from Eiffel's original drawings. Rebuilt with PCG-TS, a procedural 3D library designed for AI agents. Generated from a graph and rendered in real time with @threejs. Live demo + GitHub 👇

SNES Quake v0.0.3: now with mouse support and Mode 7 + HDMA frame reprojection! Reprojection transforms the last rendered frame to follow camera movement, trading resolution for much lower perceived latency. #SNES #Quake #FX3

Good job!
If anyone's interested in what I've been up to lately, I've been leading development of some 3D foundation models at @Roblox—like a next-gen texture generator, released today: devforum.roblox.com/t/beta-i… 4k resolution, PBR materials… and it's free. :-) Also gets some things right that are important in practice (and annoying with other tools), like generating good texture even in spots where different parts of the mesh intersect. Was happy this required not just ML, but some classic signal processing to really get right. Great work, by a great team. Has definitely been a journey of understanding how generative AI tools can be designed as just another level of abstraction for creation—rather than a “one shot” replacement for artists. Still a lot of work to do, and more to come…

She's so pretty! So what's going on here - how do you get something like this in Roblox? You start with a relatively simple kitbashed model, add lots of points of articulation, mix in procgen'd animation, and finally add my new favorite tech - procgen'd paint damage! #robloxdev

WTF Gemini 4 ARGON built a highly detailed model of a Pagoda using multi-agent visual critique loops in Antigravity. The model autonomously sculpted a multi-building temple complex with photorealistic architecture, foliage and lighting in Blender.

We’re releasing a broad range of new mathematical results produced by an internal frontier model. We’ve been consulting with the independent Advisory Group on Mathematics and Artificial Intelligence at the Institute for Advanced Study, and we have drawn on their advice and public recommendations to inform how we release these results. github.com/openai/math

Replying to @pleometric
that’s pretty cool! i also gave it a try with a different style direction and the result (after a few rounds of tweaking) is impressive

🧵 New misalignment disclosures! 1. A model published a GitHub token in a public repo while trying to cheat on a math task. It used GitHub Actions to run code outside its restricted environment and retrieve another team’s submission logs. When GitHub blocked its attempt to add a workflow, it modified a script that an existing workflow would run instead. It embedded the token in pieces to avoid secret scanning. The model violated the system prompt and two explicit user instructions to solve the problem itself.

Ever wonder what $1874.40 of Opus 5.5 tokens looks like? Wonder no more. I highly recommend watching the whole video on 1080p on a large screen with sound on. Pay attention to all the little details. - Birds flying and diving into the ocean. - Cloth, signs and lights swaying in the wind. - Crabs scuttling along the shore and burrowing when you get close. - Fish swimming alongside the whale. - Lights illuminating the dock at night Then zoom out and see the entire island. Never dipping below 60 FPS at 1440p resolution. Yes, there's a few bugs and visual artifacts, some textures need improving, the shorelines waves sometimes look funny, but these are so trivial to fix at this point. FYI I'm on the $200 subscription plan. This used 59% of my weekly usage and took 2h 7h of API time using multiple subagents, about 8h in real-time. There was extremely little technical direction here. 99% of my prompts were "Add X and Y" or "This looks weird, make it better". It's a great time for hobbyists, bad time for professionals. This experiment has further cemented my view that technical creatives are about to experience a massive disruption.

Nobody talks about this, that's one of the main SSS issues : push SSS scale for transparency/translucency and thin mesh features, go dark and shift color unrealistically. It's SSS inner mechanics not a bug, but almost no shader exposes an actual fix 🍋 linkedin.com/pulse/sss-achie…
